AVStoDVD 2.2.2 is really slow for me (first time I tried AVStoDVD). Just ~25fps with a 2.66GHz Core2Quad and default settings, I tried to convert a 40min 720p MKV (H264+AC3) with QUenc (~24fps) and HCenc (15fps@1-pass) as a test. RipBot264 and DVDRebuilder work with normal speed for me (Win7 Home Premium 64bit). Any ideas what I can do to speed it up or narrow down what causes the slow encoding?

One test isn't out and out proof, but I did a DVD-RB Pro conversion on my quad with HC 0.23 HC 0.24 May beta and HC 0.24 Sept. beta. I deleted all intermediate files between tests and used the same source with the same settings, 4 instances of HC 2 pass best profile.

The first 2 runs the video processing time was 55 minutes. But the Sept. 0.24 HC beta came in at 50 minutes. I couldn't see any qualitative difference. For @10% speed up it may be worth some copying and renaming.

edit: the other consideration is running 4 instances of HC will be with multi-threading disabled, whereas with AVStoDVD you will be running a single instance with mult-threading enabled if you're on a multi-core. So mileage may vary a bit on that score. Still, I doubt the new HC will be slower in that scenario.

I have a 23.976 fps source video. In AVStoDVD, I set the output to NTSC. But when AVStoDVD is almost finished, it gives an error message saying that the framerate is not DVD compliant. I checked the framerate and it was still 23.976 fps indeed (so not pulldowned to 29.97 fps). Why is it not pulldowned?

you should not be surprised that a 720p movie is (decoded and) encoded slowly, even on a quad core. It depends from a lot of factors: installed codecs, system cleanliness, other tasks running in background, etc. You may improve AVStoDVD speed by selecting a different AVS resizer (i.e. BilinearResize) and edit the default encoding settings (toggle on '+Settings'/'Edit encoder command parameters at runtime').

Take note that usually HCenc is faster than QuEnc in multicore systems.

Thanks for your reply! I'll try it again with the improvements you suggested. I guess I was just surprised because almost everything I did before on this PC (encoding from DVD to H264 2-pass, 720p H264 to 576p H264 2-pass and DVD9 to DVD5 HCenc 2-pass) was more than twice as fast.

I just used that file as a test case for AVStoDVD. It's from my Battlestar Galactica Season 1 HDDVD, encoded to 720p for the old HTPC.

To better understand the cause, please post the complete log file.
Just a guess: what decimal separator is setup in your system? If it is "," change it to "."

Let me know the results. Your test on brand new HW/OS is very important for me, because I usually develop AVStoDVD on an old PC (Athlon XP 1800+ with XP Pro) and debug it on a early Core2 duo...

Hi MrC. I'm new to AVStoDVD and am trying to feed it a target bitrate. That works just fine when I use Quenc CBR 1-pass or HCEnc VBR 2-pass, but not for the HCEnc OPV 1-pass profile; the bitrate of the video it produces is way off. Is it supposed to work that way, or is this a bug?

Hello Mr. C - Yes I tried more than once and with different files, but al files were recored with the same camera and in the same format. it says the avs file was succesfully created, do you want to replace existing files with it and i said yes, the error is "can't find AVSInfo.txt", then error reading .avs file trial #5. I tried to just add the avs file also but got the same read error.

Sorry if this has been mentioned but thread search isn't finding it. I set the default properties for minimum audio bitrate of 224 but every time I see the command window during audio processing it says 192.

If I enter a label text and force a new line, then the second line is lost when I reload the project. If I look at the project file the line break is saved there as a true line break instead of some sort of code:

Hi Anthony, the problem is not releated to the 'Join Title' function but to the AviSynth script info reading routine, that somehow cannot output the info file AviSynt.txt within a reasonable time. May I ask you if your system is fast (new) or slow (old)?
Anybody else have the same problem?

Hi Sjakko, it is supposed to work that way: OPV 1-pass is a Q-predictive technique that aims to fill the output space you have put in your project. BitRate is a secondary output, so it can be inaccurate. OPV 1-pass is a good compromise between quality and speed.
If you want to exactly target the BitRate you should use CBR 1-pass or VBR 2-pass.

Greetings, Filbert

Hi Filbert, no, it is not possible. Anyway you can easily edit the project a2d file (it is a text file) and sobstitute the paths.

Are you sure you have set the new Preferences *before* adding the title and going to see the audio properties?

by "command window" what do you exactly mean? The dos window showing Aften ac3 encoding progess? If you set 224 kbps in the Preferences and you see 224 in 'Title Edit'/'Audio', then Aften should run using that bitrate... something is missing to me. Could you post (or send by email) a log file?
